I can't tell very well from the photos, but I think that 1982 ad must have been from after they revamped the early design. That was probably around 1981 if I'm right.
Could these be re-posted? When I click on the little red X I'm redirected to ImageOcean.net....... Don't know what to do once I'm there to view photos..... Maybe the problem is mine.... What should I do?
